Proper way to move Rigidbody GameObject

Question

I just started learning Unity. I tried to make a simple box move by using this script. The premise is, whenever someone presses \'w\' the box moves forward.

Answer 1

Try this:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerMover : MonoBehaviour {

    public float speed;
    private Rigidbody rb;


    void Start () {
        rb = GetComponent();
    }

    void Update () {
        bool w = Input.GetKey(KeyCode.W);

        if (w) {
            Vector3 move = new Vector3(0, 0, 1) * speed *Time.deltaTime;
            rb.MovePosition(move);
            Debug.Log("Moved using w key");

        }

    }
}

Use Input.GetKey(KeyCode.W) for getting input.
EDIT NOTE: To move the object relative to its initial position use rb.MovePosition(transform.position+move) rather than rb.MovePosition(move)
